Strengths Comparison

Carbon Fiber Polycarbonate Strengths

  • Extremely stiff; useful where flex must be minimal
  • Surprisingly affordable in some brands

TPU Strengths

  • Perfect layer adhesion; extremely impact resistant; nearly indestructible
  • Great for combat robots, tactical/rough-use parts
  • Rubber-like parts (gaskets, grips, bumpers, wheels)

Considerations

Carbon Fiber Polycarbonate Caveats

  • Feeding can be difficult unless spool is close/direct-fed

TPU Caveats

  • Slow printing; retraction can cause jams (especially in Bowden setups)
  • Stringing is common
  • Very moisture sensitive; wet TPU prints poorly
